Hi Barry,

if ACK is not received, an interrupt will be got and related register
status can show this error. that is just a common feature in almost
all i2c controllers? so the naming is confused. i just copied it from

for a change.

the mail webpages and clients really fails to show the difference. i

Not all of them. gmane looks OK both in web-interface and via NNTP.
